peer route-policy export (BGP-IPv4 multicast address family view)

Function

The peer route-policy export command specifies a route-policy for filtering routes to be advertised to a peer.

The undo peer route-policy export command deletes a specified route-policy.

By default, no route-policy is configured for the routes to be advertised to a specified BGP peer.

Format

peer peerIpv4Addr route-policy policy-name export

undo peer peerIpv4Addr route-policy policy-name export

Parameters

Parameter Description Value
peerIpv4Addr

Specifies the IP address of an MBGP peer.

The address is in dotted decimal notation.

policy-name

Specifies the name of a routing policy.

The name is a string of 1 to 200 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

After a route-policy is created, the peer route-policy export command is used to apply a Route-Policy to a peer so that the routes advertised to the peer can be controlled. To be specific, only the necessary routes are advertised to the peer. In this manner, route management is implemented, the scale of the routing table is reduced, and fewer network resources are consumed.

Prerequisites

If the command specifies a route-policy that does not exist, use the route-policy command to create the route-policy.

Configuration Impact

If the peer route-policy command is run for a peer group, all the members of the peer group inherit the configuration.

The peer route-policy command is mutually exclusive with the peer route-filter commands.

Binding a route-policy after a BGP peer relationship is established may cause peer flapping.

Example

# Apply a routing policy named policy1 to the routes received from a peer.
<HUAWEI> system-view
[~HUAWEI] route-policy policy1 permit node 1
[*HUAWEI-route-policy] quit
[*HUAWEI-bgp] peer 1.1.1.1 as-number 100
[*HUAWEI-bgp] ipv4-family multicast
[*HUAWEI-bgp-af-multicast] peer 1.1.1.1 enable
[*HUAWEI-bgp-af-multicast] peer 1.1.1.1 route-policy policy1 export
